CLEANING BOLTS 0F FLOUIINGr-MILLS.

Specification of Letters Patent No. 11,039, dated June 6, 1854.

L i i To @ZL/whom @may concern Be it known that I, VILLIAM CANN, of the town of Black Rock, in the county of Erie and State of New` York, have invented; a new and Improved Mode of 'Cleaning Bolts inFlouringor Grrist Mills; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

In the accompanying drawings Figure 1, is a perspective View of the chest showing the bolt and the cleaner as they are seen when the mill is going, and the cleaner in operation, and Fig. 2, is a transverse view of the chest showing an end view of the bolt and shaft on which it turns, and an end view of the shaft to which the cleaner is attached.

In the grinding of wheat in all flouring mills it is of the utmost importance that the bolts should be kept free from beards and other obstructions, which clog up the meshes of the bolting cloth, so as to enable the mill to be run without cessation.4 In grinding spring or damp wheat, and wheat mixed with oats, the cloth of the bolt bel comes pasted up, by,the damp flour and filled with the beards of the oats, so as entirely to yobstruct the bolting.A When bolts become obstructed in this way, the mill has to be stopped and the bolts cleaned by brushing or shaving takes much time, and there is great danger of cutting and otherwise damaging the bolts by shaving.

The object of my invention is to clean the bolts fro-m all obstructions of every kind without stopping the mill, or the grinding, and without resorting to the process of shaving and bushing. It also does away `with the necessity ofthe use of the knocker used in many mills.

The nature of my invention consists in providing the bolts used for bolting flour in flouring mills with an instrument which I call cleaner to be made of common cloth of any kind, or other flexible material, which cleaner is to be attached to, and suspended from a shaft, or rod, running horizontally above and parallel with the bolt, thence falling over and coming in contact with the bolt, forces or knocks the beards or other substances which obstruct the meshes of the bolting cloth back This process into the interior of the bolt, whence they reasonof 'beingpasted by dressing the flour made from damp wheat, or` when the meshes of the bolting cloth become obstructed or clogged up by beards or other foreign substances. This cleaner entirely does away with the necessity of stopping the mill for the purpose of cleaning the bolts by brushing, shaving or any of the ways in use among millers; it saves the time usually spent in so cleaning the bolts; prevents the exterior wear and tear occasioned to the bolt by shaving and renders the grinding of damp wheat and the bolting of flour made therefrom perfectly feasible. n

To enable others skilled in the art to make and use my invention I will now describe its const-ruction and operation.

I constructmy bolts in any of the forms in common use among millers, and afx over the bolt a rod, or shaft, which may be made either stationary or revolving, running the entire length of the bolt and horizontally with it, as is shown in letter 13, of the accompanying drawings, to which rod or shaft, I attach a piece of cotton, woolen or other cloth, or other flexible material, of the same length as the bolt which it is designed to clean, as shown in the accompanying drawings in letter ,C, which cleaner may be twelve, or fifteen inches in width, or of such other width as the size of the bolt may render necessary. The cleaner being thus attached and suspended as shown in letters ings, in Fig. l, in such a manner and at such a distance from the bolt as to allow the cleaner to come in contact with and bear upon the bolt, a light attrition is produced by which the beards and other substances are prevented from lodging in the meshes of the bolting cloth, and are forced back into the interior of the bolt whence they are carried od in the channel made for their discharge.

From the lightness and flexibility of this cleaner it may be constantly used without any damage to the bolt, and when not used it may be turned over the rod or shaft B in the accompanying drawings.

I surround the bolt also my cleaner by llt! 95 B and C in thev accompanying drawa box, or chest, as shown in the accompanying drawings in letter Gr, in the manner commonly adopted in grist mills.

In the accompanying drawings letter D represents the bolt; letter E the door to the chest; letter F the space inside the chest; letter A the end of the shaft on Which the bolt turns.

Vhat I claim as my invention and desire to secure by Letters Patent is- The application to flouring bolts, of a brush, or cleaner, as herein described, which will prevent they bolts of iouring mills from becoming clogged up With and obstructed by beards and other sub- 15 l purpose the aforesaid cotton, Woolen, or 20 other cloth, or other flexible material, substantially the same and which Will produce the desired effect.

WILLIAM CANN.
